Title: Process and Apparatus for Electro-Junction Thermography
IPC: B41M5/20
Filed: 1967-09-14
Abstract: 1,183,966. Copying by scanning. PHONOCOPY Inc. 14 Sept., 1967 [15 Sept., 1966], No. 41916/67. Heading H4F. [Also in Divisions G1 and G2] In a method of graphic reproduction an electric current is passed between an electrode 14 and a metal foil 11 to produce local heating at the junction, the temperature rise on the opposite side of the foil being used to produce a visible reproduction. The current is varied (e.g. in binary form) in accordance with data 22 to be recorded and the electrode is scanned over the foil by means 16 so that the reproduction is built up point-by-point. The foil has a lower thermal conductivity than copper and preferably less than 0À85 cal./sec./sq. cm./C./cm.); aluminium and stainless steel are referred to as suitable materials. The foil has a thickness (e.g. less than 0À001 inch) which is substantially less than the diameter of the electrode. This results in practice in the corresponding elemental area in the reproduction having a diameter approximately one-half that of the electrode. The electrode is maintained in contact with the foil by a pressure means 15 exerting a force (typically 4-15 grams) sufficient to penetrate any oxide film or lubricant on the foil surface. The stylus may be formed of carbon, vitreous carbon, titanium, tungsten carbide, copper tungsten or 2% thoriated tungsten. The return current connection to the foil is made by a support platen or roller. Three modes of operation are envisaged for producing a visible indication in response to the temperature rise. In the first (that illustrated in Fig. 1), the metal foil is coated with a non-pressure transferable film of thermotransfer material 12 and placed in contact with a sheet of ordinary paper 13. The material 12 provides a good adhesion to the metal until melted and resolidified, when it forms a stronger bond with the paper. A specific example is given based on ethyl cellulose with Sudan deep black dye which is applied to an aluminium foil in a solvent of amyl acetate and ethyl alcohol. Reference is also made to the use of polyvinyl acetate, polyethylene and Carnauba wax. Nigrosine may be used in place of Sudan dyes and the coating may be pigmented rather than dyed. Alternative solvents are acetone, methylethyl ketone, toluene and dioctyl phthalate. Reference is also made to U.S. Patents 3,054,692, 3,048,695 and 2,939,009 for suitable thermotransfer materials. The coating should preferably have a softening-transfer point in the range 65-180 C. In the second mode of operation, Fig. 4 (not shown), the foil is uncoated and brought into contact with a known heat responsive recording paper. In the third mode of operation, Fig. 5, the foil 11 is again uncoated but is used in conjunction with ordinary paper 13 and an intermediate tissue 31 which carries a thermo-transfer material 12<SP>1</SP>.
